'IMPRQVEM EMT n STOVES.

Specification forming part of Letters Patent No. 209,557, dated November5, 1878; application filed April 9,,1878.

To all whom it may concern:

Be it known that I,JOHN H. GooDFELLow, I

of the city of -Troy, in the county of Itensselaer and State of NewYork, have invented certain new and useful Improvements in Stoves,described in the following specification, reference being bad to theaccompanying drawings,

in which- Figures 1 and 2 represent a vertical section V one end andoutside of the fuel-chamber. Fig.

characters refer to corresponding parts in the various figures, Ais thefuel-chamber. B is a cut-off, which may be formed of a plate or ofgrating, or, substantially as shown, formed of a plate, a, and gratingor bars I), and is provided with arms 0 0, extending from the upper andouter portions of thecut-oif around and outside of the adjacent cornersof the firebox to supporting-bearings c c at the outside of the endwalls, D D,'of the chamber A, all constructed and arranged in relationto the fire-box in the manner substantially asshown, so as to permit.the cut-off B to be moved to and'fro edgewise in the arc of a circlefrom its position next to and outside of the front side wall, E, of thefuel-chamber to that indicated by dotted lines in Fig. 2 above thefuel-supporting grate, and across, or partly across, the lower part ofthe chamber A, in such a manner as to form, when in such latterposition, a support to the fuel in such chamber above such cut-off, sothat when the. fuel-supporting. grate is withdrawn or dumped the ashesand clinkers between it and the cut-off will fall into the receptaclebeneath, the thickness of the layer of ashes so removed being regulatedby the distance the cut-off B (when in position of dotted lines, Fig. 2)and the fuel-supporting;

grate are adjusted from each other.

nected therewith, as herein described. The

resistance of the fuel in the chamber A is generally sufficient toprevent the cut-off B'fromfalling from its position at the side of thefirebox; but to otherwise retain the cutoff in this position, especiallywhen the chamber A is empty, or nearly so, I employ a catch, H, attachedat d to the casing I of the stove, and engaging with a notch orprojection, e, on the said cut-off, or any device equivalent thereto.

Though the fuel-supporting grate may be constructed and arranged in itsplace in the stove so as to be removed or dumped in any suitable mannernot to interfere with the abovedescribed to-and-fro edgewise movement ofthe cut-off B, I prefer to construct such grate F withvbearing-lugs J Jat or near its side op- G is a shank formed on oneot' the supportpositeto the cut-off B, and to so support and arrange it with reference to thechamber A and cut-off B that when such cutoff is caused to move towardthe position indicated by dotted linesB in Fig. 2 this grate F can, ifdesired, be caused to move simultaneously to the position shown in thesame figure by means of any .suitable device therefor; but I prefer tooperate the cut-off B and grate F simultaneously, by providing thejournal J with a fixed arm, K, projecting forward, and connecting itwith a strap or link, L, to the arm 0 of the cut-off.

The link L may be provided With a notch or recess, f, to receive aprojection, g, on the arm K, so as to be readily disengaged therefromwhen the grate F and cut-01f B, and parts connected therewith, are inthe position shown in Figs. 1, 3, and 5, to permit the side of the grateF next to the cut-off B, to fall away from the chamber A, as shown inFigs. 2 and 4t, for the purpose of allowing the whole contents of suchchamber to fall into the ash-pit below, the link L having suflicientlength beyond the recess f to rest against the lug g when disengagedtherefrom, so that when the cut-ofl' arm 0, with link L theretoattached, is moved to the position indicated in dotted lines in Fig. i

4, or the grate F is raised to the position shown in Figs. 1 and 3, thelink will again engage with the arm K.

I am aware it has been heretofore proposed in a number of instances tosupport the fuelsustaining grate of stoves at or near its rear edge, soas to permit its opposite side to fall away from the fuel-chamber; and Iam also aware it has been heretofore proposed to sup- .port such gratein its horizontal position by means of a catch engaging therewith,neither of which devices do I claim as of, my invention.

What I claim as my invention is 1. In a stove, the cut-off B,constructed and arranged in combination with the fuel-chamber A,substantially as shown and described,

-so that when such cut-off is unemployed in sustaining the upper portionof the contents of the fuel-chamber A while a lower portion thereof isbeing removed, as herein set forth, the said cut-off can be retained orsupported in a vertical, or nearly vertical, position next to andoutside of one of the side walls of said fuel-chamber.

combination with the chamber-A, substantially, as shown and described,and provided with mechanism for simultaneously operating said cut-01fand grate, in the manner set forth. 5. The cut-oh" B, grate F, havingbearings J J and arm K, or'its equivalent, and connecting-link L,constructed and arranged in combination with the chamber A, and tooperate substantially as shown and set forth.

6. The cut-off B, provided with supporting-- arms O G, constructed andarranged together substantially as shown and described, so as to becapable of being employed in combination with the chamber A and itsfuel-sustaining grate, in the manner substantially as set forth in theabove specification.
